skates whereby to facilitate .the quick starting and stopping movementsof a skater by tilting the toe of the skateldownwardly.

'An' important object of theinvention is to provide a. brake attachmentof this character which may be easily and quickly mounted in position ona conventional type of roller skate without necessitating any changes oralterations in the construction thereof.

A still further object is to provide a device of this character ofsimple and practical construction, which is eflicient and reliable inuse, relatively inexpensive to manufacture and otherwise well adaptedfor the purposes for which the same is intended.

Other objects and advantages reside in the details of construction andoperation as more fully hereinafter described and claimed, referencebeing had to the accompanying drawings forming part hereof, wherein likenumerals refer to like parts throughout, and in which:

Figure 1 is a side elevational view;

Figure 2 is a bottom plan view;

Figure 3 is a transverse sectional view taken substantially on the line33 of Figure 2;

Figure 4 is a perspective view of the attaching plate or the brakeblock;and,

Figure 5 is a fragmentary longitudinal sectional view takensubstantially on the line 5--5 of Figure 3.

Referring now to the drawing in detail wherein for the purpose ofillustration I have disclosed a preferred embodiment of the invention,the numeral 5 designates the sole plate of a conventional roller skateto which the front wheel truck 6 is secured by a bolt or screw 1. Abrace 8 extends from the truck forwardly thereof to a brace socket 8a atthe under side of the sole plate to permit limited movement of the truckand brace when the skater is turning.

The present invention comprises a brakeblock attaching plate 9 ofelongated form which is positioned under the sole plate 5 forwardly ofthe truck 6 and having its rear end curved downwardly as shown at ill apredetermined degree and formed with an opening II to receive the boltor screw 1. A longitudinally extending slot 12 is formed in plate 9forwardly of its downwardly curved rear end portion for receiving thebrace 8 and brace socket 8a of the wheel truck to prevent swinging ofthe plate toward either side of the skate.

5 Claims. (Cl. 28011.2)

i A rubber block I3 is recessed as at M in its upper surface to receivethe front end of plate 9,

the block having ametal .plate l5 embedded therein for threadedengagement by screws I6 threaded through openings IT in the front end ofplate 9 and through the upper portion of block l3 as shown in Figure 3of the drawing.

The bottom surface of block l3 forwardly of its transverse center line[8 is inclined upwardly as shown at H! and rearwardly of the center linel8 the lower surface of the block is also inclined upwardly as shown at20. In the operation of the device the plate 9 is secured to block l3 bythe screws 16 and the plate 9 is secured to the under side of sole plate5 of a skate as indicated in Figures 1 and 2 of the drawing So that theblock 13 will lie under the sole plate 5 at its toe portion and in frontof the front wheel truck 6.

The forwardly inclined portion I9 at the under side of the block is cutat an angle to bear flatly on the floor or ground when the toe of theskate is tilted downwardly whereby to serve as a brake for the skate orto facilitate the starting motion of a skater from a standing position.

In view of the foregoing description taken in conjunction with theaccompanying drawings, it is believed that a clear understanding of thedevice will be quite apparent to those skilled in this art. A moredetailed description is accordingly deemed unnecessary.

It is to be understood, however, that even though there is herein shownand described a preferred embodiment of the invention the same issusceptible to certain changes fully comprehended by the spirit of theinvention as herein described and the scope of the appended claims.

Having described the invention, what is claimed asnew is:

1. A brake attachment for roller skates having a front wheel truckprovided with a screw threaded fastener and an upwardly inclined bracefor the truck, said brake attachment comprising a plate having a pair ofopenings for receiving the fastener and the brace to hold the plate atthe under side of a skate, and a brake block secured to the under sideof said plate.

2. A brake attachment for roller skates having a front wheel. truckprovided with a screw threaded fastener and an upwardly inclined bracefor the truck, said "brake attachment comprising a plate having a-pairof openings forreceiving the fastener and the brace to hold the plate atthe under side of a skate, said plate having a front end portionpositioned under the toe of ing the first named plate to hold the blockfrom turning movement, and means securing the first and second namedplates to each other to hold the block at the under side of the firstnamed plate.

4. A brake attachment for roller skates having a front wheel truckprovided with a screw threaded fastener and an upwardly inclined bracefor the truck, said brake attachment comprising'a plate having a pair ofopenings for receiv- -'ing-the fastener and the brace to hold the plateat the under side of a skate said plate extending forwardly under theskate, -a brake block "having a recess in its top to receive'said'pla teand said block also having'an attaching 'plate'emb'edded therein, andfasteners'securing the first and sec- 4 end plates to each other toholdthe first named plate in the recess of the block and to hold the blockat the under side of the first named plate, said block having bevelledfront and rear edges at its under side.

5. The combination with a roller skate having a front wheel truck and aforwardly inclined brace for the truck, of a brake attachment com,prisingan elongated plate positioned under the skate forwardly 'of thewheel truck and attached at its rear end to the truck, said plate havingan opening receiving the brace to hold the plate against lateralswinging movement, and a brake block secured to the under side of theplate at its front end,
